Product Description
Filter precious protein solutions with confidence using one of the lowest protein-binding membranes available. These sterile vacuum filter systems pair a filter funnel with a receiving bottle, so you can clarify or sterilize media and buffers and store the filtrate in the same vessel. Volumes from 50 mL to 1000 mL and three pore sizes cover everything from small aliquots to bulk media prep.
This listing is for NEST catalog number 344103: Vacuum Filter System with Receiving Bottle, 1000 mL, 0.45 µm PVDF Membrane, Low Protein Binding, Sterile, Case of 12 (12 x 1). The hydrophilic PVDF membrane delivers high flow rates and throughput with low chemical extractables and broad chemical resistance, except to strong acids and bases. Units have a polystyrene cup and cap with an ABS neck, are E-beam sterilized to SAL 10⁻⁶ and are produced in a cGMP, ISO 13485 facility. Lots are tested free of pyrogens, cytotoxins, DNase, RNase and DNA, and each unit is individually bagged. Order it from LIGHT LABS alongside the rest of your NEST plastics and consumables.
Key Features
- Low Protein Binding – PVDF minimizes loss of proteins and other biomolecules
- Complete System – filter funnel and receiving bottle in one sterile unit
- High Flow Rate – hydrophilic membrane filters quickly with high throughput
- Three Pore Sizes – 0.10 µm for mycoplasma reduction, 0.22 µm for sterilization, 0.45 µm for clarification
- Sterile and Tested – E-beam sterilized to SAL 10⁻⁶ and lot tested free of pyrogens and nucleases
- Broad Chemical Compatibility – resistant to most solvents except strong acids and bases
